I used WEN for years and was getting to the point that I just wasn't getting the results I wanted. Switched to Tweak'd and it did take 2-3 wks to work thru the build up on my hair from WEN, but once it did, it lathers up nicely and the conditioner, just a little goes a long way. I still use a pump of WEN as leave in as I do need the extra moisture. I also like that you don't need to use as much product as WEN, I was never comfortable with the "if it's not working just use more" advice. If a product is high quality you should use less, right?
Also, in regards to the Tweak'd scrub to use once a week - it's amazing and you will find your hair absorbs the conditioner even faster.
Overall, my hair, just below shoulder length, combs out much easier in the shower and I have much less hair in the drain. Color and highlights last 12-16 wks before I need to touchup and never need a full color, just a partial on the outgrowth.
So far each product of Tweak'd I've tried, lives up to the hype and performs nicely.
